Because extra proton left over is not bonded to the NADH molecule. Only NADH goes on to the Electron Transfer Chain. Plue, NAD+ can only bond to one hydrogen.
NAD can accept 2 protons from NADH, forming the reduced state: NADH2
NAD+ gets oxidized by accepting electrons (and protons) during redox reactions. It is reduced to NADH when it accepts these electrons.
During glycolysis, NAD+ acts as an electron carrier molecule. It accepts two electrons and a proton to form NADH. This is important for the oxidation-reduction reactions that occur during glycolysis, allowing for the transfer of electrons and the generation of ATP.
NADH+ provides electrons for the é transport chain.
NAD and NADH function as coenzymes, meaning that they help to catalyze the breaking down of complex sugar molecules into various intermediate stages during the Krebs cycle. NAD + readily gains electrons from these intermediate sugar molecules and is reduced to NADH2. The main goal of the Krebs cycle is to release energy from glucose (sugar) and oxygen and release carbon dioxide and water. NADH is important because by breaking electrons off of the big complex sugar molecules, it allows CO2 to be released and also gains energy from those electrons. NADH molecules then carry those electrons into the electron transport chain where NADH is reoxidized to NAD+ releasing that energy.

NAD+ is reduced. It becomes NADH.
NADH is reduced compared to NAD+ because it gains electrons and a hydrogen ion to form NADH during cellular respiration. In this process, NAD+ acts as an electron carrier that accepts electrons and a hydrogen ion from substrates being oxidized, converting it to NADH.
When a molecule of NAD gains a hydrogen atom, it becomes reduced to form NADH (nicotinamide adenine dinucleotide). This reduction reaction involves the transfer of electrons from the hydrogen atom to NAD, resulting in the formation of NADH.
They form FADH2 and NADH
The main purpose of pyruvate reduction to lactate during fermentation is to convert NADH to NAD plus. Early in the glycolysis process, you'll see that there's a step where NAD plus gets reduced to NADH, and then an ATP is produced.

NADH+ provides electrons for the é transport chain.
NAD+ picks up two electrons and one hydrogen atom, forming NADH. This reduction reaction allows for the transfer of energy in biochemical processes such as cellular respiration.
